The invention relates to a symmetrical boost DC/DC converter, comprising two magnetically coupled chokes, one of which is connected to a negative DC voltage input of the boost DC/DC converter and the other is connected to a positive DC voltage input of the boost DC/DC converter, such that a symmetrical topology with separate DC voltage inputs is obtained, the coupled chokes have three cores arranged in series and connecting cores connected to the cores in each case at the upper and lower end regions of the cores, and at least one winding belonging to one of the chokes is arranged around each of the two outer cores, and the intermediate core has no winding and either has at least one air gap and/or is at least partially formed from a powder material of low magnetic permeability and is thus used as a magnetic energy store.
提出了一种对称的升压DC/DC转换器,其具有:两个磁耦合的扼流圈,其中一个扼流圈与升压DC/DC转换器的DC负电压输入端连接,而另一个扼流圈与升压DC/DC转换器的DC正电压输入端连接,使得得到了具有分开的DC电压输入端的对称的拓扑结构,其中,耦合的扼流圈具有三个串联布置的芯体、和分别在芯体的上端区域和下端区域处与之连接的连接芯体,并且围绕两个靠外的芯体分别设置有至少一个从属于其中一个扼流圈的绕组,并且中间的芯体不具有绕组并且要么具有至少一个气隙和/或至少部分由低磁导率的粉末材料形成,并由此被用作磁储能器。
